E-Invoice Integration Methods: Custom Integration or Portal?

E-invoice integration is an automated data bridge that connects a business's sales and accounting operations directly with tax authority systems. When dozens of orders flow through your desk every day, establishing this infrastructure eliminates time waste instead of issuing invoices manually one by one.

Official Portal or Custom Integrator API?

If you are a business processing no more than 20–30 orders per month, the free portal might initially serve your needs. However, when you reach volumes of 50 or more orders per day, the portal quickly turns into an operational nightmare.

Custom integration, on the other hand, automatically generates the invoice right when an order is placed on your e-commerce site and emails it directly to the customer. While eliminating manual human error, it also allows you to manage return and cancellation processes seamlessly synchronized with your ERP system.

Cost and Speed Analysis: Which Choice Is More Profitable?

At first glance, using the portal directly seems free of cost, but the spent staff labor hours turn out to be significantly more expensive in the long run. During intense campaign periods where dozens of invoices must be issued per minute, only a robust infrastructure can prevent bottlenecks and crashes.
